Effects and features of the present invention, and a method of achieving them will be apparent with reference to the embodiments described later in detail together with the drawings. However, the present invention is not limited to the embodiments disclosed below and may be implemented in various forms.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, and when describing with reference to the drawings, the same or corresponding constituent elements are assigned the same reference numerals, and redundant descriptions thereof will be omitted. .

1 is a schematic configuration diagram of a plant management system using a powerless smart pot sensor and a virtual plant to which NFC technology is applied according to the present invention, and FIG. 2 is a view for explaining the growth process of a virtual plant according to the present invention, 3 is a block diagram showing the configuration of a smart flower pot sensor according to the present invention, Figure 2 is a view showing an example of the use of the smart flower pot sensor according to the present invention, Figure 3 is another example of the smart flower pot sensor according to the present invention It is a block diagram shown. Referring to, the plant management system includes a smart potted plant sensor 100, a mobile terminal (eg, smart phone 1), and a server 300.

The smart flowerpot sensor 100 includes an NFC tag 10 for receiving induced power from the NFC reader 2 of the smartphone 1, a humidity sensor 30 for measuring the humidity of the flowerpot 200, and the NFC tag A control unit 20 that receives the induced power from 10 and supplies it to the humidity sensor 30, receives signal data from the humidity sensor 30, and relays it to the NFC reader 2 through the NFC tag 10 Includes.

The smart flower pot sensor 100 may further include a temperature sensor 40 that receives induction power through the control unit 20 and measures the surrounding temperature of the flower pot. At this time, the control unit 20 further includes a function of receiving signal data from the temperature sensor 40 and relaying it to the NFC reader 2 through the NFC tag 10. Such a smart flower pot sensor 100 will be described in detail below.

The mobile terminal is equipped with an NFC reader 2 for transmitting inductive power to the NFC tag 10 and receiving humidity signal data from the NFC tag 10, and an app for providing virtual plant content is installed.

The server 300 receives humidity signal data from the mobile terminal and provides virtual plant content including virtual plant sympathetic content corresponding to the humidity signal data. The sympathetic content may be content corresponding to humidity signal data and temperature signal data.

The virtual plant content includes virtual plant and sympathetic content. The virtual plant is a virtual plant provided on the app of the mobile terminal, and grows in sympathy with the plant of the pot 200. The sympathetic content may be an image showing the status of a virtual plant according to the tagging frequency of the NFC reader 2 and the NFC tag 10, humidity signal data and temperature signal data, and such images are tagged within a predetermined time, for example. If the frequency is high, it is determined that the communication with the real plant is excellent, and the virtual plant can be expressed with a bright expression or gradually growing. Conversely, if the tagging frequency is low or not, it is determined that the interaction with the actual plant is low, and the virtual plant may be expressed in a depressed expression or gradually faded. In addition, if the cultivated plant maintains the proper temperature and humidity through the temperature and humidity check according to the tagging, it is judged that the plant management is excellent, and the virtual plant can be expressed with a bright expression or gradually growing. If the tagging frequency is low or not, even if the cultivated plant maintains an appropriate temperature and humidity, the virtual plant can be expressed with a lazy expression. On the other hand, if the cultivated plant does not maintain an appropriate temperature and humidity through the temperature and humidity check according to the tagging, it is determined that plant management is negligible, and the virtual plant may be expressed as a depressed expression or gradually withered. However, if the tagging frequency is high, even if the cultivated plant does not maintain the proper temperature and humidity, the virtual plant can be expressed as a look that asks for water or asks for the proper temperature.

In addition, the virtual plant may be expressed in different shapes rather than facial expressions or actions according to the tagging frequency of the NFC reader 2 and the NFC tag 10, and humidity signal data and temperature signal data. For example, if you have good sympathy (meaning a high frequency of tagging), and even good plant management (meaning to maintain the right temperature and humidity), you will be expressed as a colorful, beautiful, or cute plant, and a sympathetic state. Poor and poor plant management can be expressed as ugly or tacky plants.

Meanwhile, if tagging between the NFC reader 2 and the NFC tag 10 is not performed within a set period, the app may provide an alarm to induce tagging. In addition, the app helps not to neglect plant management by providing an alarm so that tagging with the NFC reader 2 and the NFC tag 10 occurs more than once within a limited time.

In addition, in the present invention, when the sympathetic state is good and the excellence in plant management reaches a certain level, the virtual plant becomes a complete body, and one more seed can be given. A virtual plant that has reached a complete body can be transferred to a virtual flowerbed to produce points over time. Points can be used when purchasing various items that can grow virtual plants, or when purchasing various vouchers such as coffee vouchers. In addition, given seeds can be grown into a new whole body, and as the number of whole bodies increases, the amount of point production increases, so it plays a role of providing motivation to manage the actual plants well. Various exchange vouchers, such as coffee vouchers, can be provided as income such as advertisements when using the app.

Hereinafter, a smart flower pot sensor according to the present invention will be described with reference to FIGS. 3 to 5. 3 is a block diagram showing the configuration of a smart flower pot sensor according to an embodiment of the present invention. Referring to FIG. 3, a powerless smart flower pot sensor using near field communication (NFC) technology according to the present invention includes an NFC tag 10, a control unit 20, and a humidity sensor 30. The powerless smart flowerpot sensor may further include a memory. In FIG. 3, the NFC tag 10, the control unit 20, and the humidity sensor 30 may be implemented as a single device having all functions of each part, or may be implemented as different devices and combined.

The NFC tag 10 supplies power collected through energy harvesting to the control unit 20 and the memory and humidity sensor 30. For example, the NFC tag 10 is an induction generated by the mobile terminal when a mobile terminal (for example, a smartphone 1, a tablet PC, etc.) including the NFC reader 2 approaches the NFC tag 10 Power may be supplied to the control unit 20 and the memory and humidity sensor 30. That is, the NFC tag 10 may obtain power from the mobile terminal using energy harvesting technology and supply the obtained power to the control unit 20 and the memory and humidity sensor 30.

In addition, the NFC tag 10 may collect humidity signal data from the humidity sensor 30 based on the signal measurement command received from the NFC reader 2. The controller 20 may store the humidity signal data measured by the humidity sensor 30 in a memory.

In addition, the NFC tag 10 receives a read-out command for reading the humidity signal data from the NFC reader 2 and transmits it to the controller 20. And, the controller 20 transfers the humidity signal data read from the humidity sensor 30 to the NFC tag 10 according to the read command, and the NFC tag 10 can transmit the humidity signal data to the NFC reader 2 have. That is, the NFC tag 10 may relay the humidity signal data measured by the humidity sensor 30 to the NFC reader 2. The mobile terminal may display the humidity signal data transmitted to the NFC reader 2 to the user.

The controller 20 may be connected to the NFC tag 10 and the humidity sensor 30 to perform an operation according to a command of the NFC reader 2 received by the NFC tag 10. That is, when the signal measurement command of the NFC reader 2 is transmitted from the NFC tag 10, the controller 20 measures the humidity by controlling the humidity sensor 30, and converts the measured value into humidity signal data to a memory Can be saved on. In addition, when the read command of the NFC reader 2 is transmitted from the NFC tag 10, the controller 20 may read the humidity signal data stored in the memory and transmit it to the NFC tag 10.

The memory may store humidity signal data according to an instruction of the controller 20 and may provide the stored humidity signal data to the controller 20.

4 shows in detail a usage example of a smart flower pot sensor and a humidity sensor 30 according to an embodiment of the present invention. Referring to, the humidity sensor 30 may receive power from the NFC tag 10 and measure the humidity of the flower pot. The humidity sensor 30 may include an amplifier and a filter. The amplification unit may amplify the humidity signal received by the first and second electrodes 31 and 32, and the filter may remove noise from the amplified humidity signal. When a signal measurement command is received from the NFC tag 10, the controller 20 may analyze the humidity signal received from the humidity sensor 30 to generate humidity signal data, and store the generated humidity signal data in a memory.

Hereinafter, with reference to FIGS. 3 and 4, the operation relationship of the powerless smart flower pot sensor using the NFC technology according to the present invention will be described.

First, the NFC reader 2 of the smartphone 1 recognizes the unique number of the NFC tag 10. In this case, the unique number of the NFC tag 10 may include a user identifier (UID) and a serial number. A method for the NFC reader 2 to recognize the unique number of the NFC tag 10 may follow standards such as ISO 14443, ISO 15693, or Felica. In the process of the NFC reader 2 recognizing the unique number of the NFC tag 10, the induced power may be transmitted from the NFC reader 2 to the NFC tag 10.

Thereafter, the smartphone 1 transmits a signal measurement command for measuring humidity to the NFC tag 10. And the NFC tag 10 transmits a signal measurement command to the control unit 20, and transmits a response (ACK) to the NFC reader (2). Thereafter, the humidity sensor 30 measures a humidity signal. Thereafter, the measured humidity signal is transmitted from the humidity sensor 30 to the control unit 20, and the control unit 20 (or NFC tag 10) converts the transmitted humidity signal into humidity signal data and converts the converted humidity signal data. It can be stored in the memory (or the memory of the NFC tag).

Thereafter, the smartphone 1 transmits a read command for reading the humidity signal data stored in the memory to the NFC tag 10. The time point at which the smartphone 2 transmits the initial read command may be a time point in which a predetermined time elapses after receiving a response to the signal measurement command. In addition, the read command may be repeatedly transmitted according to a predetermined time interval. Meanwhile, the read command transmitted from the smartphone 1 may include a specific address of the memory.

When the NFC tag 10 receives the read command, the NFC tag 10 transmits the read command to the control unit 20, and the control unit 20 reads the humidity signal data stored in the corresponding address of the memory, and the NFC tag 10 Transfer to. Thereafter, the NFC tag 10 transmits the transmitted humidity signal data to the NFC reader 2 of the smartphone 1.

In this case, the stored humidity signal data may be transmitted in units of data blocks. At this time, when a data error or data loss occurs due to a failure in NFC communication, the smartphone 1 may maintain integrity of the humidity signal data by retransmitting the read command. Meanwhile, even while signal data is transmitted in response to the read command, the control unit 20 may continuously measure the humidity signal at predetermined time intervals through the humidity sensor 30 and convert it into humidity signal data. 20) can store the converted humidity signal data in the memory. That is, the operation of reading the stored humidity signal data by the controller 20 and the operation of storing the humidity signal measured by the humidity sensor 30 as humidity signal data in the memory may be independently performed. The humidity signal measurement of the humidity sensor 30 may be continued after the signal measurement command is received until power supply is stopped or a new signal measurement command is received.

Meanwhile, since the memory capacity is limited, when humidity signal data is stored in all storage spaces of the memory, the oldest signal data stored in the memory may be deleted and new humidity signal data may be stored in the deleted storage space.

5 is a block diagram showing another example of a smart flower pot sensor according to the present invention. Referring to, the smart flower pot sensor according to another embodiment includes an NFC tag 10, a control unit 20, a humidity sensor 30, and a temperature sensor 40. The temperature sensor 40 may be independently configured, and may be configured in a form combined with the NFC tag 10, the controller 20, and the humidity sensor 30. The temperature sensor 40 receives power from the NFC tag 10, measures the temperature around the flower pot, and the measured temperature is transmitted to the smartphone 1 through the controller 20 and the NFC tag 10.

As described above, the smart flowerpot sensor 100 obtains power from the mobile terminal including the NFC reader using the energy harvesting technology of the NFC tag and supplies it to the NFC tag, the control unit, and the temperature and humidity sensor. The temperature and humidity information of the flower pot can be transmitted to the mobile terminal without power. Therefore, the smart flowerpot sensor 100 can be maintained for a long time, and the maintenance cost is low.
